I've tried making bootable usb but failed. First I imaged my 8GB usb with dd method as per Kali documentation. It shows No Installation Media Found error after booting from USB. After that I tried Unetbootin, YUMI and Universal USB Installer but it fails. Only the windows tool mentioned in documentation named "Win32 Disk Imager" works.
Any clue why other methods didn't worked for me?
